Rafflesia tuan-mudae Becc. (Rafflesiaceae) is endemic to Borneo and was recorded from Sarawak and probably Kalimantan. Previous records showed that Tetrastigma rafflesiae (Miq.) Planch. (Vitaceae) is the only host plant for R. tuan-mudae. In this study the host were collected each time R. tuan-mudae was observed or collected. Out of 20 Tetrastigma specimens collected infected by R. tuan-mudae, 14 were identified as T. diepenhorstii (Miq.) Latiff while 6 belonged to T. rafflesiae. Therefore, a new host for R. tuan-mudae is recorded and descriptions for each host are presented.

1. Introduction as the host plant for many Rafflesia , namely, T. curtisii (Ridl.) Suess., T. diepenhorstii (Miq.) Latiff, T. glabratum Rafflesiaceae is a plant family that consists of eight gen- Planch., T. papillosum Planch., and T. rafflesiae Planch. [1, 9– era Apodanthes Poit., Bdallophytum Eichler, L., 11]. However, the latter is the host plant for most Rafflesia Mitrastema Makino, Pilostyles Guillemin, Rafflesia R. Br. ex species and also for zippelii (Blume) Spach [1, 9]. Gray, Rhizanthes Dumort., and Griffith with about Establishing the identity of the host plants is difficult mainly 55 species recorded. All members in this family are obligate because they were usually not collected together with the parasitesandrootlessandhavenochlorophyllandtherefore Rafflesia [1]. Observations of 771 herbarium specimens from are dependent on the host plants for water, nutrients, and various herbaria such as BO, KEP, SAN, SAR, SING, SNP, survival [1]. Currently, the Rafflesia consists of about and UKMB showed that there were only two records of 34 species and is distributed in the Southeast Asian region Tetrastigma as the host. An example is shown by R. keithii [1–6]. (Coll. number SNP4088) where T. diepenhorstii is mentioned. Some species of the genus Tetrastigma (Miq) Planch. Moreover, the hosts that were collected were sterile with no (Vitaceae), a woody vine, are the host plants for Rafflesia fruits or flowers, thus making reliable identification virtually species [1]. Tetrastigma is distributed mainly in the Asian impossible [1].
